To all whom it 'may concern:

, Be it known that l, SAMUEL C. CARTER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Transmission lt/iechanism, of which the following is a specification.

Objects of this invention are to provide for automobiles and the like, a satisfactory direct drive transmission which has few parts, may be readily thrown into and out of gear, and changed to and from high, inF termediate, and 10W speed with great ease and convenience and to apply the' power from the driving shaft to the driving Wheels of the m'achine through practically differential means of very simple construction to prevent slipping of the Wheels in turning corners.

Another object is to provide an auto1no .invention Figure 1 is a fragmental plan of the invention as applied in an automobile, 'a fragment of one of the drivinfr Wheels bein shown, it'

beingunderstood that the driving W-heels are'duplicatcs. Some of the parts arebroken and partly shown in section. Fi 2 is a sectional elevation on line :r2 x2, ig. 1, on

Fig. IO-is a section on line alo-acl", Fig. 3.- Fig. 101L isan enlarged detail of a fragment of Fig. .10.

1 designates a driven shaft having rotatably fixed thereon a plurality of disks 2 and 3 likewise extensible y thereof.

The disk 2 lis provided with a single gear face 6 which 1s fixed to the outer periphery thereof and is used to reverse the machine. Coacting with said driven shaft is a driving 'shaft 57 which is connected with the prime mover, and which is extensible for the purpose of compensating for variations in the axial alinement of the shaft and which is A pinion or bevel gear 8 is integrally united with said driving shaft 7. The lower part 9 ofsaid shaft 7 1s squared to accommodate a plurality of gears 10 and11 of varying sizes which are slidable on the lower part of said shaft and adapted to be thrown into during the rotationl mesh with the concentric gear facesll of the disk 3, thus variably transmitting power from it to the driven shaft and subsequently -to the wheels.

' The shaft 1 is enveloped Vby a casing 12, and the train of gears above described 1s inclosed in a gear case or housing 13 rigidly secured to the casing 12 of the shaft 1 as well as to a part of the vehicle.

The extreme end of the driving shaft 7 is )rovided with a collar 15 and operates in the caring 16 formed by a support 17 which extends upwardly within the gear case and is made a part thereof.

The casing 12 enveloping the shaft 1 does not extend entirely through said gear case 13, but is broken off in the hub 18 thereof to accommodate a toothed collar 19 which is secured to the hub 18 but which is loose upon. the shaft 1. ihis toothed collar 19 is engaged by a similar toothed collar 20 loosely mounted upon the shaft and adapted to re main stationary during the revolution of the driven shaft, and whose function is to force said clutch collar'191jout of engagement with the collar 20, whereby the entire shaft 1 is y closing the orifice 28 in wheel, as shown at 33,

the inner faces of said toothed collar 2O is a ball thrust bearing 21 designed to offset and take up the wear incident to the operation of the toothed members against the disk surfaces. l

Wheels 22 are mounted upon the casing of said driven shaft, and the operation of the wheels is determined by a drum 23 rigidly fixed on to the extremity of the shaft 1 and provided with duplicate pockets 24, the concavities of which are formed by a centrally and angularly-extending undulation or rid gc 25 centrally dividing the pockets. These pockets terminate in abrupt walls or noses 26 on oppositely-disposed sidesl A collar 27 surrounds said drum andis provided with peripheral orifices 28 extending centrally therethrough. Each orifice 28 is 'arranged to accommodate a ball 29 which is interposed between said drum and collar and acts to lock the collar on said drum when the shaft has been shifted to a position which' .will allow the ball to abut against the abrupt wall formed by the pocket.

If the ball is shifted to the opposite side a reversal of the wheels is effected. If, however, the ball is allowed to ride upon the ridge 25 the wheels are free to revolve independently of the machine or the motive power of the engine. This ball is held in place in its respective orificeA by means of a small screw 30 forming a cap and partially order to allow the ball to rise and fall as the shaft isshifted.

A huh casing or shell 31 is likewise secured to said collar 27 by means of a screw 32, and this shell is screwed on to the hub of the whereby the .motion from the'` shaft is transmitted to the wheels of the vehicle. Thus, as the balls in the pockets are caused to change their positions from one pocket to vthe other they engage the oppositely-disposed walls formed by the pockets, and'l thus engaging, lock the collar together with the casin or shell 3l, allowing the shaft to rotate eiter forwardlxT or backN wardly according'to the position of the halls. In this manner rotar motion is imparted to the wheels directly from the drurnthrough '.1 dine? the medium of the driven shaft. This construction enables one wheel to travel faster than the other when making turns, thus avoiding what is commonly known as skidof .the inner wheel. The outer wheel, in describing the arc of a circle, of necessity travels with greater velocitythan the inner. wheel. To compensate for this variation in the degrees of revolution, I have devised this l methodof locking the wheels in such manner upon the drum which i'sfastenedto theaxle, that as the turn is made, the outer wheeldescribing the greater radius of a circlep may travel4 considerably faster than the shaft upon which it is mounted. If, for instance the inner wheel is revolving at say 250 eraser revolutions per minute, the outer wheel will revolve at a speed grdater than that of the inner wheel, though the axle and the inner wheel are revolving in harmony with the prime mover.

The operation is accomplished in substantially the following manner c-The drum iskeyed to the driven shaft with which it revolves. The collar to which thewheel is secured surrounds the drum, and when in its' operative position the ball locks the collar against the drum, thus revolvingr it with the axle. In a straight line the wheels revolve at equal speeds,'but when a turn is made the 'outer wheel, which is bound to cover a greater amount of space,-together with the collar surroundin the drum,-automatic ally releases itself from the lock inasmuch as the proportionately increased speed of the wheel to that of the shaft'earries the collar around the drum faster than the drum itself. is revolving; at the same time causing the ball to travel forwardly-and out of its pocket, and to ascend in the orifice in thel collar, thus permitting of a variation in the velocities of the drum and the collar. When the turn has been completed and the necessity of a more f outer wheel than wheel, 1s dispensed with,

speedy revolution of the that of the inner the ball falling back into its normal position;

viz.,-in the pocket, and abutting against the wall formed by the p0cket,--again locks the collar on to the drum and the revolving shaft, and equalizes the speed between the two wheels. This is automatically accomplishcd, as is evident. To operate the driving shaft 7 l provide a sleeve 34 situated between two rigid collars or rings 35 made fast with said shaft and rotating therewith. This sleeve has an extension 36 and a nger 37 provided with a notch 38. A rod v39 is pivoted on to said extension 36, asshown On to the upper end of the gear casing is a pivot dog 41 having attached thereto a rod 42 extending to the foot of the operator in the body of the vehicle, as shown at 43. One part ofsaid dog is curved, as seen at 44, and provided with a link 45. Said link 45 extends downwardly and engages a notch 57 provided in the sleeve 52 and notch is intended to lock the rod against movement. The rod is likewise provided with another notch 58, which is ada ted to receive the link 45 ivotally vattache to the dog 44. This notcli 58 acts as a lock when the dog 44 has been operated or raised to enfgage the notch 38.provided in the iin'gcr 37 of' the sleeve 34 andv revents the accidental disen agement of t e pinions. v A

n order to operate the driving shaft the operating lever 43 is pressed down, which in turn raises the part 0i" the dog 41. Thereupon the arm'39 is operated, and it in turn forces back the shaft 7 until the extremity cf the rod 49, which l I 55 the -olutehcollars/19 and 20.

the arms 'from their operative positions.

The arm (il is slidahly mountedupon the shaft 62 for the purpose of allowing' e letersl movement thereof for engaging the other levers extending through the block 59. The extreme end'of the sleeve is provided with e lever 65 which operates all of the erms'respectiv'ely. The block is provided with guide-Ways 66, 67, ond 68 into which the arm 61 slides in the act of operating the arms 39, 51 and 56. .The gravity pewl has s. rearward extension 69 operating 'against an incline 70.
